Ocean currents control the climate around the world. When they suddenly stop, it unleashes an endless cascade of weather disasters including blizzards, superstorms, drought and rapid sea level rise.
Surviving the bone-chilling cold, deadly blizzards and darkness of an Alaskan winter takes courage, cunning and remarkable endurance. In the raw beauty of windswept mountain peaks, icy tundra and snowbound forests, this is the story of the tough and resourceful characters that face up to the ultimate challenges of this untameable land.
(PART 1) A team of experts and explorers venture into the Danakil desert in Northern Ethiopia to investigate the incredible geology of the area, and to find out how the people and their animals survive in the hottest place on earth. Kate Humble investigates how tough life is for an Afar woman; Steve Leonard wants to learn about the relationship between the Afar and their animals, and to help with animal medicine where he can; Dr Mukul Agarwal looks at the health issues faced in this most hostile of environments; earth scientist Dougal Jerram looks at the extraordinary volcanic activity of the region and the part it plays in the bigger geological picture of the Rift Valley; and biologist Richard Wiese searches for extreme life forms in the boiling soil of a massive volcanic fissure.
The enduring luster of gold, the conductivity of copper, the strength of steel—the special properties of metals have reshaped societies and defined eras; they have such an important role in human history that entire ages have been named after them. But what gives metals their astounding characteristics? From the perfect ring of a bronze bell to the awe-striking steel construction of Beijing’s “Bird’s Nest” stadium, how have humans perfected metalworking? And how have metals enabled our modern hi-tech world? Explore the science of metals with chemists and engineers as they literally test the mettle of metals and investigate how these remarkable materials have ushered humanity from the Stone Age to the stars.
